A process was developed to deposit highly conductive features on plastic films and papers. In this process, a reactive silver ink, which contains a weak reducing agent and is stable at room temperature, is directly cast or printed on a pre-coated substrate at room temperature. The strong reducing agent coated on the substrate instantly reacts with the ink on its surface and cause the rapid silver deposition locally. As the heat generated from the reaction is quickly transferred to the upper part of the ink, it initiates silver reduction reaction in the section, resulting in the continuous silver build up from the surface. Silver features with a conductivity almost the same as that of bulk silver and a thickness of up to 1 micrometer can be obtained from this bottom-up silver reduction and thus silver growth process. The whole reduction process happens at room temperature within minutes without any external energy applied.
